A chemical equation consists of the chemical formulas of the reactants (the starting substances) and the chemical formula of the products (substances formed in the chemical reaction). ... Using IUPAC nomenclature, this equation would be read as "hydrochloric acid plus sodium yields sodium chloride and hydrogen gas."

write down the modification which have been made in the chemical equat...
Modification in the Chemical Equation:
- Original Equation:
Zn + H2SO4 -> ZnSO4 + H2
- Modification:
The modification made in the chemical equation is the addition of state symbols to indicate the physical state of reactants and products.
- Modified Equation:
Zn(s) + H2SO4(aq) -> ZnSO4(aq) + H2(g)
- Explanation:
The addition of state symbols is important in chemical equations as it helps in distinguishing between reactants and products in different physical states.
Here, 's' represents solid, 'aq' represents aqueous solution, and 'g' represents gas.
In the modified equation, Zn is in solid state, H2SO4 is in aqueous solution, ZnSO4 is also in aqueous solution, and H2 is in gaseous state.
This addition of state symbols provides a more comprehensive understanding of the reaction and the physical states of the substances involved.
